Heat pump device

Abstract

A heat pump comprises a heat pump circuit which is comprised by connecting the compressor, hot water supplying heat exchanger, a pressure reducing device and an evaporator into an annular part by cold catalyst tube, and an air feeding device which varies the capability of the evaporator; and the air feeding device is actuated after a specified time from the actuating of the compressor.

Description

technical field [0001] The present invention relates to a heat pump device such as a hot water supply machine equipped with a heat pump circuit composed of a cold catalyst tube connected to a compressor, a heat exchanger for hot water supply, an expansion valve and an evaporator, and particularly relates to a The refrigeration cycle stabilization technology. Background technique [0002] Figure 9 A conventional heat pump device is shown, and a compressor 101, a radiator (condenser) 102, a decompression device 103, and an evaporator 104 are connected by a cold catalyst pipe 105 to circulate the cold catalyst. In addition, in the hot water storage device, the hot water storage tank 102 and the heat absorber 102 are connected by a water pipe 108 , and water is circulated by a heat pump 107 . 102 A heat exchanger used as a radiator in a heat pump device and a heat exchanger used as a heat absorber in a water storage device, that is, the heat absorption of the cold catalyst of ...

AI Technical Summary

Problems solved by technology

As a result, the orbiting scroll is separated from the fixed scroll, and the cold catalyst in the high-pressure compression chamber leaks into the low-pressure compression chamber, so-called overturning occurs, and sufficient compression cannot be performed, and the circulation amount of the cold catalyst flowing in the refrigeration cycle is reduced. Freezing ability is also reduced

[0007] In addition, if the thrust acting on the back of the orbiting scroll is increased in order to suppress the overturning caused by the low compression ratio, under the operating conditions of the high compression ratio, excessive thrust will be generated on the orbiting scroll to cause abnormal wear, Therefore, there is a problem that the thrust acting on the back of the rotating scroll cannot be increased too much

[0008] In particular, when starting the operation of the heat pump, if the blower is started in conjunction with the start of the scroll compressor, the pressure of the evaporator will increase and the pressure difference in the refrigeration cycle will decrease. The operation of the scroll compressor was unstable before it became overturned, the reliability of the scroll compressor was reduced, and the cold catalyst tube vibrated greatly and made abnormal noise
